To all whom t may concem:

Be it known that l, RALPH H. BrNNs, a citizen of the United States, and a resident of the city of New York, in the county of 5 New York and State of New York, have invented certain new and useful improvements in Closure Locks, of which the followinO is a specification.

ly invention relates to a lock, and is particularly intended for use in connection with a closure member of a type hereinafter set forth.

vlt is a well appreciated fact that one of the most eiiicient forms of closure is that which employs two series of arms spaced one from the other, which arms are formed with headed portions adjacent their outer. ends, an actuating member beine provided which o o-operates with the arms or causing the headed ends of each series of the same to extend into the space existing between. the bodies of the arms of the other series to thus interengage these arms, or which actuatin member upon being properly moved wi cause a disengagement of the arms to thusl open the closure.

However, objection has been noted to the useof a closure of this nature, in that the actuating member has often been accidentally'- moved when the arms are in closed position, so that the closure has been opened. A lso` in certain associations in which aclosure of -this nature is employed,- a certain strain has been exerted upon the closure, and this strain quite often causes the actuating member to move along the arms and effeet a detachment of one series from the other of the same.

Having these and other diiiiculties inmind, my present invention aims to provide a lock for a closure. of this nature which lock will prevent anymovement of the actuating member with respect to the arms other than upon lsaid actuating member being deliberately moved. f j 4 A further object of my invention is that of providing a lock which is primarily intended for association with the actuating 'member, and which will require a deliberate manipulation of its body in orderto permit of a travel of the actuating member along the arms.

A still further object of the present invention is that of roviding a device of the character stated which will serve to exert a locking inuence upon the parts named, which induence will be in direct proportion to the separation strain exerted upon the closure parts.

Another object of my present invention is that of providing a closure lock which may be substituted for` the pull member commonly associated with the actuating-member, it being noted that the lock, in addition to performlng the functions aforementioned,

will also act as a pullunember to enable the actuating member to be readily manipulated when it is desired.'

Still another object of my invention is that of providing a lock of the nature specie :Hed which will embody an extremely simple form of construction, and thus be free of mechanical difficulties, and which will also becapable of being placed upon the market at a nominal figure.

With these and further objects in mind the present invention consists essentially of a locking element movably carried by the actuating member and adapted, when in operative position to engage the parts lof the closure in such a manner as to prevent a A movement of one of the same with respect to the other. l

Reference is had to the attached sheet of drawin as illustrating a practical embodiment of my invention. lit willbe seen in these drawings that;

Figure l is a front view of a conventional form of closure of the type afore-identied, together with an actuating member therefore, the latter being shown in the position assumed during the closing operation of the former, the latter carrying my improved loclr.

Figure 2 is a view similar to Figure 1 but showing the partsin their final or locked position. Y

Figures 3 and d are longitudinal sections taken along the lines 3 3 and, 4f-4 and in the direction of the arrows indicated in Figv100 ures l and 2 respectively, and

Figure 5 isv an enlarged fragmentary Aview of a detail of construction hereinafter described.

It will be noted in these views that the conventional type of closure afore-referred to has been illustrated, and thus the reference numeral indicates the strips or base portion, which each mount one series of arms 7 spaced one from the other 'and formed with heads as .at -8, it being. .understood that, as

xaforementioned, the heads of each series of arms extend into the space existing between the other series of arms, and are brought into and removed from this' position by means of the actuating member 9 moved alon theclosure proper, it being furtherI note that ,in accordance with conventional construction, thisactuating member is provided with a rail 10 for the mounting andl traversing `of a pull member by means of' which the actuating member is moved in the' manner specilied.

However, in lieu of the pulll member commonly employed at this point I provide an v element which serves as a lock as well as a pull member, and this element includes a plate 11 which has its upper end bent as at l12 to provide-a pair .of inwardly extendingarms13 for Aslidable engagement with the rail 10. vThe plate is also preferably shaped toconform to the shape of the actuating 'member 9, and to thus'pres'ent a neat'appearance. A pair of lingers 14are formed integral with the plate 11, and are provided at points spaced from the arms 13, these fingers 14 being bent inwardly and downwardly -and extending into a plane beyond that into which .the arms 13 extendfor a purpose hereinafter Is'peciied. Finally it will be noted that the plate 11 (referring to its locked position as shown in Figures 2 l and 4) has its lower end portion.- bent inv than the thickness of the lower outer edge of the actuatin'g'member 9.

In use it willbe understood that the parts wardl and also'slightly upwardly as at'15,A

and t is end portion is of a length greater are normally the position shown in Figures 2 and 4. In this position the ngers 14 bear against the stop members 16 provided one at the up erend of each of'theseries of arms 8. O viously this will prefvent any movement. of theactuating member along the arms of the closure', incident to the fact that the late 11 is at the upper limit of its travel, a ong the rail 10. Also assuming that a pull is exerted u on the two series of arms in opposite directions, which. would normally cause a movement of the actuating member along uthe same, and a consequent opening of the closure, it will be appreciated that the stop member 16 will bear against the lower edges. of the fingers' 14 and tend to push the same upwardly. 'This will cause the plate 11 to tend to rock around the arms 13 which 'will actas aA pivot, andthus the lower end 'of the' .plate will be thrown in-4 wardly and will have its outer edge rmly engage the arms to thus preclude any movei ment of the actuating memberl with respect u tothe closure, and in fact it will be under- 'Y arms toseparate, the

stood that the greater the tendency of the thrust upwardly against the fingers 14, thus greater will be the.

consequently increasing the thrust inwardly on the part of the bent portion 15, and locking the parts more lirmly.

`The described operation of; the device is due to the fact that-the locking fingers 14 in the locked position shown in Figures 2 and 4 are presented in a plane beyond theplane including the axis' of pivot .arms 10, so that any upward pressure on lockingv ngers 14 causes the pivot plate 11 to tend to press more closely against the face oi actuating member 9 and interlocking members 7.

Assuming however that it is desired to move the actuating member 9 with respect to the arms to disengage the same, one fromv the other, it will' be understood that this may readily be accomplished by simply swingingv the lower end of the plate 11 around the arms 13, which latter act as a pivot, thus causing the parts to assume the position shown lin Figures 1 and 3. The plate 1l may now be slid along the rail 10 until it reaches a point adjacent the lower end of the same, and a continued pull exertedupon the plate will causethe actuating member .9 to ride over the arms to ie'ifect an opening ofthe closure, it being obvious that when the parts of the vclosure are, again to be engaged that a pull upon the plate 11, in an opposite direction will cause the same to ride along the rail 10 to a point adjacent lthe upper end of the actuating member 9, and this action, if con inued, will cause` the said actuating memb r to move along the closure to the positio shown inuFigures 2 and4 subsequent to which the plate 11 may;y pe swung to the position also shown in res. Y p g'lIlhus it will be understood that the-objects of this invention have been accomplished and it will bey readily appreciated that numerou modifications' `o structure might lreadily be resorted to without in the least de-l parting from the scope of my. claims; vwhich are- 1. a closure lock, the combination with stringers carrying spaced interlocking members, and' an actuating member. embraclng `and sliding upon, said interlocking members.
